For some objects on an EcoStruxure BMS server, for example the time zone object and schedule object, you can establish a lead and shadow relationship to the parent EcoStruxure BMS server. A shadow object automatically synchronizes settings from its connected lead object. A lead and shadow relationship can only be established between objects of the same kind.
For example, an Enterprise Server and three individual Automation Servers are located in same time zone region. Instead of individually configuring all the servers time zone, a lead and shadow relationship is established. The Enterprise Server is the lead object and the three Automation Servers are shadow objects. With this relationship, the Enterprise Server time zone settings are reflected and used by the three Automation Servers.
When you set up a lead and shadow relationship, you define which object is the lead object in the properties of the shadow object. For example, to synchronize an Enterprise Server object with an Enterprise Central object, you define the lead object, in this case the Enterprise Central object, in the properties of the Enterprise Server.
A server on a higher level, such as an Enterprise Central, typically acts as the lead. However, a lead and shadow relationship can be established between two SmartX servers.
When you configure lead objects on an Enterprise Central, the shadow objects on Enterprise Servers can, in turn, control objects on SmartX server.
You can establish a lead and shadow relationship to synchronize the time on all your EcoStruxure BMS servers with the same network time server. The Date and Time object on the lead server contains the network time server addresses that are inherited by shadow servers.

You can establish a lead and shadow relationship to synchronize the time zone settings on all your EcoStruxure BMS servers. The Time Zone object on the lead server contains the time zone settings that are inherited by shadow servers.
For more information, see Synchronize Time Zone Settings .
When you have predefined content types that you want to use for specific types of folders or container objects on an EcoStruxure BMS server, you can reuse the content types on another EcoStruxure BMS server. You reuse the content types by configuring a lead-shadow relationship on the shadow object.
For more information, see Content Type Synchronization .
When you configure a schedule that controls events in a single part of a building, you might also want the same events to occur in other areas of the building. You can establish a lead and shadow relationship to synchronize the events in schedules and dates in calendars.
For more information, see Schedule and Calendar Synchronization .
When you have predefined Alarm Control Panel objects, for example user actions or alarm decorators, that you want to reuse on another EcoStruxure BMS server, you configure a lead-shadow relationship on the shadow Alarm Control Panel.
